You would've had to give an email address when you bought Pro (you would've recieved a couple of emails after you purchased...one reciept & one email with a link to your personal download page). Did you buy Pro from Lime Wire » Official Website & Free Download « for $18.88? Providing that you bought from the official site, contact limenathan (click on the blue link below) & he should be able to sort things out for you
